pg_listening_channels()

Hello,

In Postgresql 9.2 this function pg_listening_channels() returns the channels that the current session/connection listens to.

How (if it’s even possible) can I get listening channels for all sessions/ connections in the database?

With older versions I could just query “pg_listener WHERE relname = listener_name”.  Not any more, the table doesn’t exist in newer versions.

Regards,
